The comment above spoke about "this fundamental valuation number" regarding FORWARD P/E. Forward P/E is a guess (== varius analysts use various numbes == Almost always wrong sometimes in a major way). That's why I made the comment. I understand perfectly well what P/E is.

EDIT: Companies also manipulate E in various ways so even though P/E is supposedly not as fictitious as forward P/E you also have to be careful with that number.
